For any lens, the thickness at the height of a half of the entrancepupil diameter (HEP) particularly affects the ability of correctingaberration and differences between optical paths of light in differentfields of view of the common region of each field of view of lightwithin the covered range at the height of a half of the entrance pupildiameter (HEP). With greater thickness, the ability to correctaberration is better. However, the difficulty of manufacturing increasesas well. Therefore, the thickness at the height of a half of theentrance pupil diameter (HEP) of any lens has to be controlled. Theratio between the thickness (ETP) at the height of a half of theentrance pupil diameter (HEP) and the thickness (TP) of any lens on theoptical axis (i.e., ETP/TP) has to be particularly controlled.

Theoptical image capturing system of the present invention satisfies:

0.2≦ETP/TP≦3.

The horizontal distance between two neighboring lenses at the height ofa half of the entrance pupil diameter (HEP) is denoted by ED, whereinthe aforementioned horizontal distance (ED) is parallel to the opticalaxis of the optical image capturing system, and particularly affects theability of correcting aberration and differences between optical pathsof light in different fields of view of the common region of each fieldof view of light at the height of a half of the entrance pupil diameter(HEP). With longer distance, the ability to correct aberration ispotential to be better. However, the difficulty of manufacturingincreases, and the feasibility of “slightly shorten” the length of theoptical image capturing system is limited as well. Therefore, thehorizontal distance (ED) between two specific neighboring lenses at theheight of a half of the entrance pupil diameter (HEP) has to becontrolled.

In order to enhance the ability of correcting aberration and to lowerthe difficulty of “slightly shorten” the length of the optical imagecapturing system at the same time, the ratio between the horizontaldistance (ED) between two neighboring lenses at the height of a half ofthe entrance pupil diameter (HEP) and the parallel distance (IN) betweenthese two neighboring lens on the optical axis (i.e., ED/IN) has to beparticularly controlled. For example, the horizontal distance betweenthe first lens and the second lens at the height of a half of theentrance pupil diameter (HEP) is denoted by ED12, the horizontaldistance between the first lens and the second lens on the optical axisis denoted by IN12, and the ratio between these two parameters isED12/IN12; the horizontal distance between the second lens and the thirdlens at the height of a half of the entrance pupil diameter (HEP) isdenoted by ED23, the horizontal distance between the second lens and thethird lens on the optical axis is denoted by IN23, and the ratio betweenthese two parameters is ED23/IN23. The ratio between the horizontaldistance between any two neighboring lenses at the height of a half ofthe entrance pupil diameter (HEP) and the horizontal distance betweenthese two neighboring lenses on the optical axis is denoted in the samemanner.

The horizontal distance in parallel with the optical axis between acoordinate point at the height of ½ HEP on the image-side surface of thefifth lens and image surface is denoted by EBL. The horizontal distancein parallel with the optical axis between the point on the image-sidesurface of the fifth lens where the optical axis passes through and theimage plane is denoted by BL. In order to enhance the ability to correctaberration and to preserve more space for other optical components, theoptical image capturing system of the present invention can satisfy:0.2≦EBL/BL≦1. The optical image capturing system can further include afiltering component, which is provided between the fifth lens and theimage plane, wherein the horizontal distance in parallel with theoptical axis between the coordinate point at the height of ½ HEP on theimage-side surface of the fifth lens and the filtering component isdenoted by EIR, and the horizontal distance in parallel with the opticalaxis between the point on the image-side surface of the fifth lens wherethe optical axis passes through and the filtering component is denotedby PIR. The optical image capturing system of the present invention cansatisfy: 0.2≦EIR/PIR≦0.8.

In an embodiment, a height of the optical image capturing system (HOS)can be reduced while |f1|>f5.

In an embodiment, when the lenses satisfy f2|+|f3|+|f4| and |f1|+|f5|,at least one lens among the second to the fourth lenses could have weakpositive refractive power or weak negative refractive power. Herein theweak refractive power means the absolute value of the focal length ofone specific lens is greater than 10. When at least one lens among thesecond to the fourth lenses has weak positive refractive power, it mayshare the positive refractive power of the first lens, and on thecontrary, when at least one lens among the second to the fourth lenseshas weak negative refractive power, it may fine tune and correct theaberration of the system.

In an embodiment, the fifth lens could have negative refractive power,and an image-side surface thereof is concave, it may reduce back focallength and size. Besides, the fifth lens can have at least an inflectionpoint on at least a surface thereof, which may reduce an incident angleof the light of an off-axis field of view and correct the aberration ofthe off-axis field of view.
